The Cash for vote scam

A few months back when I first wrote about the cash-for-vote scam where MPs were shown holding bundles of currencies in the parliament accusing a few opposition party MPs of trying to bribe them to vote for the government in the no-confidence motion voting, I also wrote that there is nothing that is going to be done of these accused MPs.
The verdict is finally in. A panel of committee specially set-up for the investigation finally adjudged Amar Singh the main accused in the scam, not guilty. That stamped the fact that in India, no politicians can be punished.
I wonder why we spend so much money on these committees and investigations. We should rather dismiss these cases at the onset itself, so that at least we save on this money (hard earned money of ours that we pay as tax) and use that in some other better way. Here again, one would question the better way, because the better way would then be into the pockets of these politicians itself.
We need more of the peace march that we did to the Gateway of India after the Mumbai terror attacks. We need a revolution and a revolution can only happen when we, the mob wakes up.
